In the field of nuclear industry scientific research, laboratory wastewater treatment is never an option, but a rigid bottom line related to ecological security and public responsibility. CNNC's Sichuan scientific research laboratory undertakes national important tasks such as nuclear material testing, physical and chemical analysis and radioactive scientific research experiments. The generated wastewater, mixed with trace radioactive elements, heavy metals and high-strength acid-base reagents, has extremely strong particularity and harm, placing almost strict requirements on the purification depth of the treatment process and the safety factor of the equipment.

At the same time, although the daily wastewater volume of 2 tons is not large, the frequency of scientific research experiments is not fixed. High-concentration wastewater centralized discharge and intermittent shock loads occur frequently, coupled with the continuous test of the corrosion resistance of the equipment by the humid and rainy climate in Sichuan, making conventional treatment methods incompetent.

Facing these 'nuclear-grade' challenges, the laboratory introduced AiKe's AK-SYFS-HW series laboratory wastewater treatment equipment, building a solid safety barrier with modular integrated process, fully automatic PLC intelligent control and outdoor weather-resistant design. On the first anniversary of the equipment's operation, AiKe's after-sales team made a special trip to Sichuan to carry out in-depth maintenance for this core equipment, escorting the compliant discharge of every drop of wastewater in nuclear industry scientific research with professional services.

I. Nuclear Research Scenarios Are Strict, and Wastewater Governance Difficulty Escalates

CNNC's Sichuan scientific research laboratory focuses on core work such as nuclear material testing, physical and chemical analysis, and radioactive scientific research experiments. With high scientific research precision and strict experimental standards, the generated laboratory wastewater has extremely strong particularity, and conventional sewage treatment equipment can hardly adapt, with many long-standing governance difficulties.

First, the wastewater composition is complex and highly harmful, mixing trace radioactive elements, heavy-metal substances, high-strength acid-base reagents and special organic solvents. The pollutants are highly toxic and complex, and the requirements for the purification depth and safety factor of the water-treatment process far exceed those of ordinary laboratory wastewater.

Second, the frequency of scientific research experiments is not fixed, and the daily 2-ton wastewater discharge fluctuates greatly. Intermittent discharge and concentrated discharge of high-concentration wastewater occur frequently, which easily cause load shock to the treatment system, leading to incomplete treatment and non-compliant water quality.

In addition, Sichuan is humid and rainy, and the laboratory's supporting water-treatment equipment is mostly in semi-outdoor humid working conditions. The corrosion resistance, stability and anti-aging performance of the equipment are strictly required. The humid environment easily causes pipeline corrosion and component moisture failure. Coupled with the zero-tolerance environmental standards of nuclear research scenarios, the difficulty of laboratory wastewater operation and governance is greatly increased.

II. AK-SYFS-HW Series Customized Maintenance Adapts to Nuclear Industry Special Wastewater Conditions

AiKe's after-sales operation and maintenance team went to a laboratory under CNNC in Sichuan to provide free on-site special maintenance services for the AK-SYFS-HW series 2-ton/day laboratory wastewater treatment equipment that had been in use for 1 year, comprehensively building a compliance discharge defense line for laboratory sewage in nuclear industry scenarios.
The laboratory routinely undertakes core work such as nuclear-related material testing and physical and chemical analysis. The generated wastewater has a special composition, and the requirements for the stability, anti-corrosion performance and pollutant removal accuracy of the treatment equipment are extremely high. This maintenance strictly followed the safety specifications of nuclear industry scenarios. The engineers focused on the full-process investigation of the equipment's pretreatment unit, physicochemical reaction system and deep purification module, cleaned pipeline deposition impurities, calibrated PLC intelligent control system parameters, optimized the automatic dosing ratio, and at the same time tested 316L stainless steel anti-corrosion components and core treatment unit operating conditions, repairing subtle operation losses.

After maintenance, multiple sampling tests showed that all effluent indicators of the equipment stably met relevant national discharge standards, fully adapting to the continuous treatment needs of the laboratory's complex wastewater. The on-site engineers also simultaneously conducted special practical training for operators, explaining daily inspection points and emergency handling skills, further improving the enterprise's autonomous operation and maintenance capabilities.
This on-site service is a landing practice of AiKe's normalized preventive operation and maintenance for key industrial customers, ensuring the long-term stable operation of the equipment with professional original-factory services, and helping nuclear industry laboratories achieve safe, green and compliant wastewater treatment goals.
